What is Lactate Threshold & Why Does it Matter for Running?

[samuelwalker]

Been running about seven months with no idea what I'm doing. These videos help so much. Thank you. ( still lost 70 pounds )

Sample Workout: 10min Warmup, 4x8 min @LT Pace 2 min rec jog, 4x2 min @slightly faster than LT Pace 2 min rec jog, 10-15 min Cooldown.

Lactate is also produced aerobically and there are also multiple lactate thresholds, your referring to LT1. Also sub LT1 (aka zone 2) should be very easy. Also you dont get better at tolerating lactate you just get better at metabolising/clearing it and keeping it contained in the muscle. To improve lactate clearance one should do long z2 sessions.

I don't mean to be critical but this video is way off the mark. There are actually TWO "lactate threshold" points: heart rate when lactate starts to accumulate linearly with effort (LT1) and then again when it starts to accumulate exponentially with exertion (LT2). To see balanced improvement you need to train both points. Unfortunately you can't really know where they are without doing bloodwork, either in a lab or with lactate meter.

Intervals like you suggested in this video are closer to LT2, or perhaps even beyond LT2. Arguably more important is a sustained 20-40 minute run ("tempo") that is about what you could hold for one hour. It shouldn't feel miserable but it should feel tough.

How do you determine your lactate threshold pace?

[ohorguN]

I guess it would be best if you can first explain how people can determine their lactate threshold pace... before telling them to run below their lactate threshold..😅

Because im pretty sure most of the people have never even done a lab lactate threshold test...

I'm just a clueless runner. But I have a 2 part question: why would we running *under* LT threshold to improve and would runner *above* LT threshold also improve LT threshold?

[BenjaminKuruga]

Your body just seems to increase glycogen stores and improve fatty acid oxidation in majority of fiber types. Not sure it has anything to do with tolerating lactate or "pushing" the threshold.

[SwimBikeRory]

Are you saying to run at LT1 or LT2? How would you determine whis range, and what pace should you run at for threshold intervals? What about continuous tempo?

[LeoShoSilva]

What you are talking about is lactate turnpoint

I fairly new at running and I have a few questions. I’ve been running now for about 8 months. I’ve lost 130lbs so far and looking to be at 165 lost by Dec. I’ve done a few races(2 5ks and 1 10k). I just bought a HRM to find out what my lactate threshold (LT) is. I have a half coming up in 16 weeks. My question is. Do we use that LT to figure out what our running pace is for races? Or is it just for training purposes and progression only or races from 30-60 min mark? Not quite sure how to figure out what my race paces should be or if this even related to LT. I’ve done a few long run type sessions to figure out what times I can run a half at this moment and using as a base line for the training I’m in so I know if I’m improving. Anyways, any help would be welcome. Thanks.

I have no idea why but everytime I have tried to run i could never run more than a minute. Even after doing years of hard cardio. It was like I could never catch my breath.

[gytisleimonas]

What if lactate threshold run is easy jogging speed. My watch tells its 6-6.30min per km.

[casanjt]

2mins is too much rest for 8min threshold interval...

[taha.]

I get the intense feeling of my calves burning after about 5 minutes of running. Should I be worried?

I used baking soda and my LT went down, but might affect your stomach.
